CEMENTINGr-MACHINE.

To all whom it may camera:

Be it known that I, JOHN W; CosGRovE, a citizen ot the United States, residing at Medtorcl, in the county of Middlesex and State of Massachusetts, have invented certain lmprovements in Cementing-Machines, of which the following description, in connection. with the accompanying drawings, is a specification, like reference characters on the drawings indicatng like parts n the several figures." a

This invention relates to cementing machines and especially concerns those in which the material to be coated is acted upon by a cement-applying member and bya workengaging member. In accordance with t, a machine is provided by which the cement is'applied uniformly to the edges of various articles; particularly those which are sharply bent or curved, and which may readily be arranged to suit different Operating requirements. i

A feature of my invention consists of a novel workfeeding member, which, while causing an eflicient contact of the work with approximately the full width of theapply ing member does not interfere with the freedom of the work to turn in changing the directiono'f feed. In the organization illustratecl, the feeding member comprises sections which are relatively movable independently of, one another so' that they may travel at diflerent rates while the member is advancingthe work. i

Another feature concerns novel connecting mechanism `tor the work support or 'teeding member which may act from dif- :terent normal positions. A convenient form of this connection includes coperating levers which may be mounted differently with relation to one another to obtain the desired result. y

The accompanyng drawing illustrates one embodimentof the invention,

Figure 1 being a side elevation of the portionsfof a cementing machine with which this nvention ismore directly concerned, the connections for the work support being arranged 'to control' it from a normally raised position; v p

- 14: the flow from which is controlled by a alve 16 delivering the cement to an applying member consisting of a roll 18. This roll is fast upon a horizontal shaft (not shown) journaled in the upper portion of the frame 12 beneath the tank and rotated by a belt engaging fast and loose 'pulleys 22; The cement is carried from the tank to the work in pockets or depressonsQ t in the roll 18, these pockets being ina continuous series about the periphery and being longer in their dimension transversely ot' the roll. They are separated `from oneanother by relatively thin walls 26. l Vhen the pockets are thus wholly divided ifrom one another, the area of cement which each deposits upon the work tends to remain distinct from that deposited by the adjacent pockets, or even to decrease in area and draw together by coheson. This produces an interrupted and non-uniforma coating.

To prevent this, I form one or more narrow grooves 28, which are here shown as four in number, circunferentially of the roll connecting all the pockets. These grooves not only lay connecting lines of cement upon the work to break the otherwise uncoated surfaces, but also tend to causethe raised portions of cement deposite'd by the pockets to draw together or coalesce, so that the work is coated over almost theentire peripheral face of the applying roll. Thisefiect is attained without disturbing the capacity, of the pockets for ,carrying a limited quantity otcement and thus prevent flooding, a condition which would occur were the cement-carrying depression to be 'in the form of a continuous groove about the roll of the fullwidth' of the strip of cement to be applied.

For both supporting and advancing the work, an engagmg member is provided below and opposite the applying roll, this' preferably consisting of the roll substantially equal in width to the applying roll. It is carried upon a shaft 32 journalcd in elevated hearing portions 36, 36 of a lever 34 fulcrumed at 38 upon the frame 12. Bo'- tation is imparted to the roll 30 through spur gearing 40 by which the shaft 32 is j oined to the main shaft. The depth of engagement of the teeth of the gearng 40 is such as to permit the lever 34 to Swing to a limited extent upon its fnlcrum point without interfering with the driving action. The roll 30 is made up of disks furnishing sections which may rotate independently of one another, there being three of these disks here llustrated.` The central disk 42 is fast upon the shaft 32, it having a central internally threaded opening to engage a thread 44 upon a reduced portion of the shaft. Inner and outer disks 46 and 48, respectively, at each' side of the disk 42 are. mounted to turn freely. The disk 46 lies between 42 and annular shoulder 50 on the shaft abutting against the end of the lever 34, while the disk 48 surrounds the outer reduced end of the shaft and is held in place by a bolt and Washer 52. To cause the disks 46 and 48 to ofi'er little resistance to turning, anti-friction rolls 54 are interposed between them and the shaft. The effect of this sectional feed roll 'is that when cement is to be applied to *the surface along a straight edge, the positively driven disk 42 advances the work beneath the applying roll, the disks 46 and 48 rotating with it at' substantially the same rate through their engagement with' the work. Upon angular movement of the work, however, as when shoe soles being cenented along the outer edge of one of their surfaces are turned to follow the curvatnre, the rate of rotation of the disks 46 and 48 changes, the one at the outside of the curve increasing in angular velocity while that at the inside lags behind the driving disk. These rotary velocities change instantly with the ehange of direction, soethat practically no resistance to the turning of the work is offered. This, in spite of the fact that the roll 30 acts to hold the work up to the full v width of the cement-applying surface.

When the applying roll. and feed roll are in suficiently close proximity to press the work between them, it is advanced by their rotation and coated with cement over the area with which the applying roll Contacts.

' .If the feed roll is lowered, it carries the work away from the applying roll and the effective feed ceases. The 'travel uefa-the i work, so .that the application of cement may and with it the shaft 32 and feed roll,

about the' fulcrum 38. The character of the work or the inclination of the' operator may render it easier to have the feed roll normally raised in its feeding relation, to be lowered to introduce the work or stop the advance; or it may be found :preferable to have the feed roll normally lowered, from which point it is lifted after the introduction' of the work to start the cementapplying action. This invention fnrnishes mechanism which may be arranged easily and with slight changes in the elements to accomplish either result. The carrier lever 34, as here illustrated, is of the bell-crank type, it having an arm 56 dependihgfrom the upper hearing arm. With this arm 56 cooperates a second bell-crank lever 58 ;fulcrumed upon' a bracket 60 secured by wood screws 62, or' the like, to the tablelO. 'To

the lower horizontal arm of the lever 58 is pivoted a link 64 passing downwardly through a hole in' the table for connection to a treadle or other member for actuation by the operator, this' not being shown. Through the front portion of the frame 12 is threaded a screw 66 Secured by a check nut 68 hearing against the' framefi The in ner ,end of the screw 66 is so positoned that as the feed roll is raised the arin 5601:' the lever 34' contacts with it., Itthereby serves tolimit and adjust the approach of the feed roll to the applying roll. rit the opposite side of the' frame, threaded into an opening in a boss 70', is a screw 72 of considerable diameter and having an axial bore. If the feed member isto be normally-raised, as is tremity 'by means of an eye 7 6 and pin 78;to

the bifurcated lower end of the' arm 56.

tween the lever arm 56 and the inner end of the screw 72, is a helical spring 7 9, which holds the lever against the stopscrew 66 and the feed roll raised into coperation with the? applying roll. The resistance of the roll 30 to movement may be varied by turning the screw 72 and thus altering the tension of the spring 79. A spring 80, surrounding the actuatingrod 64 between the base ofthebracket 60*and the horizontal arm of the lever 58, holds'up the rod and connected actuating elements so that the feed roll may not be. lowered by their weight. A V V I If the conditions are such that anormally lowered position' of' the feed 'roll isprefer able, the bracket`60 is Secured by its screws in the reverse position illustrated in Fig, 2, another hole being bored through the table Surrounding the rodf74, and extending bee to receive the rod 64. VVhenthus located, i

the upper end of the bell-crank lever 58 rests against the opposte or rear side of the arm 56, from which the rod 7 4 with its 'surrounclng spring' been removed; "The spring 80 carrying the `weight of the actuating parts* is employed as' before, but no spring equivalent to 7 9 is required, since the weight of the lever 34 and elements' supported thereby is sufficient to normally maintain the roll at' its lowest point In plying roll and feed roll is shown a gage 84, adjustably' fixed upon the .top of the outer hearing portion 36 of the arm 34 by means of a screw 86.` 'This gage Controls, by -its contaetwith the edge of the work, the width of the strip of'cement which is applied. About the periphery of the 'feed roll at the front, or the` side from which' the work is' introduced, extends a shield 88 carried by an arm 90 fixed to the outer hearing portions 36, said shield holding the work 'from contact with this portion of the feed roll and acting to facilitate its entrance between the feed roll and the applying roll. The general operation of the machine will beobvious without further description.

Having thus described my invention, what I claim as new 'and desire to'secure by Letters Patent is: e
